This kit includes 2 components, each built and powder-coated in-house.
Total Control Over Caster and Axle Alignment
The Jeep Gladiator JT’s factory suspension suffers from insufficient caster, leading to wandering, instability, and rut tracking—especially after a lift. CORE 4X4’s Cruise Series Front Control Arm Set completely eliminates these issues, allowing for precise caster correction and axle centering. With both front upper and lower control arms, this set gives you full control over your alignment, improving steering response, high-speed stability, and off-road capability.
Key Features and Benefits
- Corrects Caster Deficiencies – Eliminates wandering, instability, and rut-following by restoring proper caster angles.
- Re-Centers the Front Axle – Ensures correct wheel placement in the wheel well, improving alignment and tire wear.
- Adjustable for Lifts (0-6”) – Optimizes suspension geometry for stock height up to 6-inch lift setups.
- Tapered Polyurethane Bushings – Reduces noise, vibrations, and harshness (NVH) for smoother suspension movement.
- Heavy-Duty Steel Construction – Built from high-strength steel tubing for superior durability.
- Recommended Pairing for Maximum Stability – Combine with our Cruise Series Front Track Bar (CRS-J-JT-FTB1) to further reduce death wobble and improve steering precision.
Two-Stage Powder Coating for Maximum Protection
Every control arm undergoes a two-stage powder coating process to ensure long-term durability and corrosion resistance: Zinc Primer Base Coat – Forms a rust-resistant barrier for extreme conditions. Customizable Top Coat – Available in 10 colors to match your Gladiator’s build while adding extra protection.
Made in the USA
Proudly designed, tested, and manufactured in Orem, UT, our Cruise Series Control Arms meet the highest American craftsmanship and quality control standards.
Optional Hardware Upgrade
- Our Front Control Arm Set installs using factory hardware.
- However, if your vehicle has rusted, seized, or worn-out bolts, we offer optional Grade 8 hardware kits for a smoother and more secure installation.
For even more front-end control, pair these with our Cruise Series Front Track Bar (CRS-J-JT-FTB1) to further reduce death wobble and optimize steering response.
